Homology is a concept in Biology that refers to similarities between different species due to shared ancestry. In genetics, homology refers to similar DNA sequences found in different species that are inherited from a common ancestor. Homologous structures in anatomy are organs or body parts that have a similar underlying structure but may have different functions in different species.
proposed hypothesis of homology based on similarity.
Homology
Homology is frequently found in organic chemistry.
homology
Physical homology, Genetic homology, and Ecological niche
Evolution
Homology- Evolved from a common ancestor Analogous- 2 similar structures that evolved differently

The key distinction between homology and homoplasy is that homology is when similar traits are inherited from a common ancestor, while homoplasy is when similar traits evolve independently in different species.

The three types of homologies are anatomical homology (similar structure), developmental homology (similar embryonic origin), and molecular homology (similar genetic sequence). These homologies provide evidence of common ancestry and evolutionary relationships among different species.
